granular or granularity
In business terms, this describes the fine details, after you drill down to get to the nitty gritty.
For example, "The price of opt-in lists is going up, but apparently there's good reason for it, due to the high degree of granularity available in these lists." In surfer-speak, it means awesome, as in "Totally tubular, dude."
